UNIVERSAL GLOBE-JOINT.

To whom it ma@ conce/M1,

Be it known that I, J osIAH BRUNO, Jr., of Lansing, in the county of Ingham, and State of Michigan, have invented a new and useful Improvement in Universal Globe-Joints; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification.

'gnre 1 is a perspective view of my invention. Figure 2 is a vertical section on the line X- X in iig. l..

Like letters indicate like partsin each figure. The nature of this invention relates to an improvement in universal globe-joints, so that the same may `be used as a coupling for lines of Shafting, in any desired position, without the projecting pins usually found in globe-joints.

It consists in a hollow globe, constructed in two parts, the interior being-itted at opposite sides with eccentric recesses and shoulders also of a solid globe, fitting and filling the interior ofthe hollow globe, andprovided with adjustable pins, which are designed to engage with the shoulders at the end ofthe eccentric recesses, each globe being provided with suitable means of attachment to the .Shaftiua A, in the drawings, represents the hollow globe, cast in two pieces, with division shown in the line B, said two pieces being secured and held together by band C.

D is a socket, forming a prolongation of the globe A, and provided with a suitable square aperture, to receive I the end of the shaft E, which is secured in place by the set-screw F, or in any other convenient manner.

G is a solid globe, so made as to iit the interior of the hollow globe A, and provided with a similar prolongation, socket, aperture, and set-screw, for a like purpose. This socket projects through the opening H, in the side of thedaollow journal, in such a manner as to operate at an obtuse angle.

I are pins. inserted in a central aperture through the globe G, and fitting and operating against the shoulders J, at the ends of the eccentric recesses K, upon the interior of the hollow globe A.

-L is a spiral or other spring, so situated within the central aperture through the globe G, heretofore mentioned, that its ends will press against they inner ends of the pins I, and retain the same in their engagement with the shoulders J.

By the construction of a joint in the manner above described, it will be readily seen that the joint may be operated at an obtuse angle, o1' in line, as may be desired; that the same revolving one way, the pins, forced outward by the spring, or their own gravity, with the centrifugal force, into the eccentric recesses, are compelled to engage with the shoulders, thereby forcing the one globe to give motion to the other. In a reverse motion, the outer ends of the pins slide along the eccentric recesses, being disengaged from the shoulders, until their outer ends are iiush with the surface of the globe G, when no motion will be communicated from one globe to the other.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The globe A, constructed in two parts, as described, l

and secured by the band G, said globe being hollow, and provided internally with eccentric recesses K and shoulders J, substantially as and for thepurposesherein set forth.

2. In combination with the above, the solid globe G, provided with a central opening, substantially as and for the purposes described. l

3. The pins I and spring L, or its equivalent, in combination with the globe G, substantially as and for the purposes set forth. 4
